What Is the FJD Trion P1?
The FJD Trion P1 is a 1 kg handheld 3D LiDAR scanner using SLAM (Simultaneous Localisation and Mapping) technology, enabling real-time point cloud capture without GPS dependency. It is designed for fast reality capture in complex indoor and outdoor environments where traditional static scanners are impractical.

When to Use the Trion P1 in London
This device excels in scenarios where static tripod scanners are too slow or inaccessible — particularly relevant for London:
- As-built surveys of buildings, plant rooms, and complex interiors
- Heritage/listed building documentation common across London
- Underground or confined spaces (tunnels, basements, service voids)
- Infrastructure surveys (bridges, highways, drainage) — a full bridge captured in 15 minutes
- Construction progress monitoring — walk-through capture between RIBA stages
- Condition surveys pre-demolition or pre-refurbishment
- Volumetric calculations and cut/fill modelling on site
It works equally well in direct sunlight or total darkness, making it more versatile than photogrammetry-only solutions.

Frequently Asked Questions
Q: How accurate is the FJD Trion P1?
Real-world relative accuracy is approximately 2cm — suitable for as-built documentation, BIM clash detection, and volumetric calculations. It is not survey-grade (which requires ±1–2mm from a tripod scanner).
Q: What is the battery life?
Approximately 2 hours of continuous scanning with hot-swappable batteries so you can swap without interrupting the scan.
Q: What data formats does it export?
Exports to .las, .pcd, .pts, and .ply — compatible with all major BIM/CAD software including Autodesk ReCap and Revit.
Q: Is the Trion P1 suitable for listed buildings in London?
Yes — completely handheld and non-contact, making it ideal for heritage and listed buildings where physical access to measure ornate or fragile details would be intrusive.
